Question

Why do bulls get angry when they see red?​

Answer 1

Explanation:

because bulls hate red

Answer 2

Actually, it doesn't. Bulls, along with all other cattle, are color-blind to red. Thus, the bull is likely irritated not by the muleta's color, but by the cape's movement as the matador whips it around. In support of this is the fact that a bull charges the matador's other cape — the larger capote — with equal fury.
